Sienna Miller Is Bringing Back the Paperbag-Waist Pant

While Men’s Fashion Week is in full swing at Pitti Uomo, its influence is being felt all around the world. Today in London, Sienna Miller made a case for a menswear-inspired silhouette that not everyone can pull off: the paper-bag pant. But Miller is never one to be intimidated by a loud pant—the Live by Night actress has been seen in everything from leopard-print leggings to wide-leg culottes. She understands that, when raising the bar below the waist, it all comes down to proportions.

In this case, her fitted jumper, trimmed in nautical red-white-and-blue piping, offset the paper-bag slouchiness. Her sleeves, which were nonchalantly pushed up to the elbow, echoed the same sense of relaxed sophistication. The loop belt cinched Miller’s waist and lent the outfit a surprisingly flattering line. Wayfarer-style shades played up the tomboyish vibes of the trouser, while suede platform sandals firmly placed the trend on solid, stylish ground.
